APPARATUS FOR BURNING EARTHENWARE.

peciflcati q ofLetterslaten l Patented Aug. 2 1913.

Application mee'armaeaieie. seri lnassmva burning earthenware and is directed to the provision of an improved device for rapidly handling such ware to effectually and evenly burn the same in a comparatively short period of time. In carryinlg forth this idea, we have-provided a kiln aving transverse flue openings therein extending longitudinall throughout its length, whereby a very unitbrm heating action may be obtained by passing hollow saggar blocks between these transverse openings. These s'aggar blocks are adapted to carrying earthen ware in any desired position and consequently, by a continuous movement, such as an endless carrier, the articles may be burned to a high degree of'perfection.

The preferred mechanism for carrying out our invention is shown in the accompanyin drawings, in which similar characters 0 reference designate corresponding parts, and in which- Figure 1 is avertical section bf the lower portion of a kiln with our invention applied thereto, Fig. 2 is a .detail view of the discharging end of the conveyer element, and, Fig. 3 is a section taken on line 33 of'the structure shown in Fig. 1.

In the drawings, the kiln is shown at 1 as having a passage 2 extending entirely therethrough, which passage is adapted to accommodate an endless chain element comprising, in its entirety, trunnions 3 and 4, sprocket wheels' 5 and 6 and driving chains 7 and 8. These driving chains 7 and 8 extend over and are driven by sprocket wheels 5 and 6 and they furnish a supportingmedium' for. a plurality of slat elements 9 which are hingedly secured together by rods 10 and complemental cars '11 and which serve as supports for 'saggar blocks to be described. These slats desirably have their outer surfaces covered with asbestos layers 12 and upon these layers 12 are to be placed saggar blocks 13 which are preferably of substantially cubical form, but

provided with'openings 14 therethrough extending transversely to the direction of travel of the chain. The upper side of this chain element is prevented from sagging by guideways 15 and this upper side is preferably disposed just below transverse flues 16 having practically continuous openingslongitudinally of the kiln, and which because of their location and the form of the saggar blocks direct currents of heated airv continually through the openings formed in the saggar blocks.

In 0 eration ofthe structure thus far describe it will be apparent that the articles of earthen ware are placed upon the saggar blocks at the left-hand side of the machine as shown in Fig. 1 and the movement of the belt in normal direction toward the right conducts the articles of earthen ware t rough the kiln and therefore necessarily into and through the zone of heat. During the assa e of the saggar blocks through t e kin, they are continually subjected to the influence of heat currents playing upon their interior walls and necessarily imparting heat by conduc tion and radiation to the articles carried upon their upper sides. The passage of the earthen ware articles throu h the kiln may be timed as desired, but each article is preferably subjected to the heatduring'a pev riod of approximately twenty minutes.

In the preferred mechanism utilized, we desirably provide tables or supports 18 and 19, although -it will of course be understood that these su ports may vary as to form.

By a simp e and apparently readily conceivable mechanism, we are enabled to burn earthen ware in a short length of time and -yet the actual workers in the art are today spending forty-eight hours in doing what we accomplish in twenty minutes.

W'hat we claim, is

A machine for burning earthen were comprising a kiln having opposed transverse flue I passages extending continuously 1011- In testimony whereof we afiix our signagitudinally of the kiln, an endless carriage tures in presence of two witnesses. for continuous movement through said kiln,
